A dual-tuner DVB-T PCIe card sold by TerraTec. This card appears to be supported from kernel 3.3 by LinuxTV drivers (not confirmed). Testing on 3.3.0 did not appear to work, while 3.4.3 works (DVB-T/C no analog). In 3.4.6 it works quite well, also tested watching two channels at the same same on DVB-C and this works.

Overview/Features

This is technically a very interesting card. The hardware is as follows:

  • Tuner #1: microtune mt2063
  • Demodulators #1: drx-3916k DVB-T/Analoge TV
  • Tuner #2: microtune mt2063
  • Demodulators #2: drx-3913k DVB-T/DVB-C
  • PCI Express x1 Bridge: Conexant cx23885

Inputs:

  • 1x Antenna (Coax)
  • 1x Remote (2,5 mm jack)

Package contents:

  • Card
  • Low profile bracket
  • Remote (+ AAA batteries)
  • DVB-T antenna
  • IR receiver
  • Windows Software & Installation DVD
  • Quick setup guide

Support

This card is supported from kernel version 3.3 (?). The microtune tuner was merged in kernel version 3.3 (see first submission).

The card itself was added upstream on LinuxTV's git repository on 2011-12-17 and may have been merged upstream.

The first frontend supports only DVB-T, but support for analogue TV is planned for kernel 3.4 or 3.5. The second frontend supports both DVB-T and DVB-C in a multifrontend device (spec's DVB v5 API).


Also, this card is a dual tuner in the sense that you can have two streams active at one frontend at the same time. This works for watching/recording two different channels at the same time or record one and watch another (So two times DVB-C or DVB-T, I only tried DVB-C myself).

Remote Control support

The supplied IR remote is not supported yet, there is generic support in the kernel module for cx23885-based DVB-cards but this does not work for this card. (modprobe cx23885 enable_885_ir=1). Another card that has the same PCIe bridge does work, see http://www.linuxtv.org/wiki/index.php/TeVii_S470

I think it's the Conexant cx23885 chipset IR receiver and transmitter logic that has to be used, see the product sheet on [1].

The remote control appears to transmit signals following the NEC IR transmission protocol, just like the TeVii S470. The remote is also used with other Terratec Cinergy cards, so the keymap is already defined in file v4l/rc-nec-terratec-cinergy-xs.c, an LIRC keymap can be found on [2] (you can compare the remote with my image below and [3]).

I modified the source code (most of it are switch statements in cx23884-cards.c and cx23884-input.c), compiled it and ran it with modprobe cx23885 enable_885_ir=1 and got the following output:

Unfortunately it did not work yet, I think it has something to do with the vendor specific frequency defined in cx23885-input.c around line 167:

Turning i2c_scan on in the kernel modul (modprobe cx23885 i2c_scan=1) gave me this output:
